Krytox is the brand name for a range of clean, specialty synthetic lubricating materials available in numerous grades for a wide range of applications. Krytox lubricants have become the product of choice where extremely high or low temperature performance, non-flammability, longevity, oxygen compatibility and resistance to aggressive chemicals are required.
Is Krytox compatible with nonmetallic materials? Yes. Krytox oils and greases have been used as plastic or elastomer component lubricants for over 40 years. For more specific information, please request K-20565, “Krytox Lubricants Plastics and Elastomer Compatibility.”
How stable is Krytox when exposed to chemicals? Krytox perfluoropolyether (PFPE) oils and greases thickened with polytetrafluoroethylene (PTFE) exhibit exceptional chemical stability. Krytox oils and greases will not react with most chemicals (with the exception of Lewis acids and alkali metals) and other lubricants, nor cause them to degrade. Krytox Performance Lubricants are not only […]
Are Krytox lubricants flammable? No. Krytox lubricants are not combustible nor do they ignite.
What approvals and certifications do Krytox Lubricants have? Krytox lubricants have the following certifications: ISO 9001 Certified Quality Management System ISO 14001 Certified Environmental Management System In addition, certain grades have the following approvals: MIL-Spec PRF-27617 approved grades for aerospace and aviation use NSF H1-certified lubricants approved for incidental food contact Independently tested and confirmed […]
Can I mix Krytox grease with other greases? The performance benefits of Krytox grease will not be realized if Krytox™ is mixed with a non-perfluoropolyether (non-PFPE) grease. The performance of the grease mixture will be limited by the properties of the non-PFPE grease in the mixture. Krytox grease will not react with the other grease […]
Is ongoing lubrication required once we’ve begun using Krytox? Re-lubrication of bearings may be required, typically every 1 to 3 months for corrugators, depending on the equipment operating temperature. For other applications, re-lubrication intervals can be from months to years—or potentially never, in the case of sealed systems.
Do I need to do anything special before using Krytox in bearings? Before adding Krytox grease to a bearing, the bearing should be cleaned of all existing greases, oils, or preservative oils used during storage. If hydrocarbon oils are left in a bearing, the oils can form carbon deposits at high temperatures, which may accelerate […]
What is the NLGI consistency of Krytox grease grades? Greases are formed by mixing the base oil with a thickener to form a grease. Krytox greases use a special high-thickening efficiency, low molecular weight polytetrafluoroethylene (PTFE) with very small particle sizes as their thickener. This is one of the most thermally stable thickeners for high-temperature, […]
Where can Krytox lubricants be used? Krytox lubricants can be used in applications where non-flammability, oxygen compatibility, materials compatibility, high-temperature stability, and resistance to aggressive chemicals are requirements. Some examples include: Automotive: wheel bearing grease, CV joint grease, universal joint grease, fan clutch bearing grease, emission air pump grease, spark plug boot lubricant, weather stripping […]
What is Krytox made of? Krytox fluorinated oils are a series of low molecular weight, fluorine end-capped, homopolymers of hexafluoropropylene epoxide with the following chemical structure: F-(CF-CF2-O)n-CF2CF3 | where n=10 to 60 CF3 The polymer chain is completely saturated and contains only the elements carbon, oxygen, and fluorine; hydrogen is not present. On a weight basis, […]
What are the different grades of Krytox GPL lubricants and their typical applications? The Krytox GPL 10X oil /20X grease series contains no additives and can be used on components that come in contact with most chemicals typically used in industry. Typical applications include valves or bearings, seal barrier fluids, instruments, and oxygen systems. The […]
Does Krytox contain silicone? No. Krytox oils and greases do not contain any silicones and there are no silicones used in processing.
What are the primary differences in Krytox oils? Krytox XHT oils have additional treatment to make them more thermally stable at temperatures over 300 °C (572 °F) and have very high viscosity to withstand such temperatures and provide adequate lubrication. Krytox aerospace oils have more strict volatility specifications and are a narrower distillation than GPL […]
